The 30-year-old from Kindersley, Sask., underwent spinal surgery a year ago and was cleared to play this season.

But he recently began experiencing back and neck stiffness.

Dorsett’s surgeon, Dr. Robert Watkins, says tests revealed that he has sustained a “cervical disc herniation adjacent and separate to his previous fusion.”

Watkins and team doctors advised Dorsett not to resume his hockey career.

Dorsett says he is ”devastated by the news” but that there is no “grey area.”

In 515 NHL games, Dorsett collected 51 goals and 76 assists.

“What I can say for certain right now is that I left it all out on the ice. I gave my heart and soul to the teams I played for and never backed down from a challenge, including this one." – Dorsett (@Twigy15) pic.twitter.com/10OmlCFotb
